How Can I Efficiently Shuffle an Integer Array in C#?

Optimizing Integer Array Shuffling in C#

For efficient random shuffling of integer arrays in C#, the Fisher-Yates algorithm offers a linear-time solution. Alternative approaches can encounter performance bottlenecks, especially as the shuffling nears completion.

The Fisher-Yates shuffle avoids these issues by employing a straightforward, yet effective, method:

1. A random index is selected from the unsorted portion of the array.
2. The element at the current index is swapped with the element at the randomly chosen index.
3. The current index is incremented, and steps 1 and 2 are repeated until the entire array is processed.

This ensures a uniformly random shuffle in O(n) time, providing a reliable and efficient way to randomize integer arrays.
